Acids and bases can neutralize each other in double displacement reactions. For example, if hydrogen chloride (a strong acid, HCl) is mixed with sodium hydroxide (a strong base, NaOH), the products are water, H2O, and salt, NaCl. Write the balanced double displacement reaction with the simplest whole number coefficients.

The answer to your question is HCl + NaOH ⇒ NaCl + H₂O

Explanation:

Data

Double displacement reaction

Balanced chemical reaction

HCl + NaOH ⇒ NaCl + H₂O

Reactants Elements Products

1 Chlorine (Cl) 1

1 Sodium (Na) 1

2 Hydrogen (H) 2

1 Oxygen (0) 1

As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.
